Question: i am 12 and my 10 year old sister is taller than me why is this

Growth depends on a lot of things – genes and the height of your parents, nutrition and hormones. I have 3 children, the youngest is over 6ft, the oldest is around 6ft and the middle is only 5ft 10 inches! Teenagers get their pubertal growth spurt so you never know what height you will end up.
